Actually, the coating on my shifter had a nick in it that just got worse in time, so I started chipping away at it, and there is a wonderful looking chrome finish underneath- I got all of the top off, but as it starts getting to the front, the coating isn't coming off so easily. I've been using a credit card as well to chip at it.
I LOVE the look of this:
